Firefox Community Forum

I am encountering an issue with the Ultimate Addon Image Gallery when viewed in the Mozilla browser. On the user's first visit to the page, the image gallery fails to load promptly, often taking a long time to display. During this delay, a black screen appears instead of the intended images, and the images do not retain their original sizes.

This issue is specific to the Mozilla browser and impacts the user experience. I would greatly appreciate any guidance or troubleshootinghttps://globalstep.com/art-page-revised-v6-33/

Firefox is verified Broken! Whatever Firefox did with its last update is causing major problems. Spent hours with the internet provider and websites trying to figure out why could not access webpages and internet accounts.

Firefox is taking forever to load pages and often just times out or never actually loading the page. When I can get to a page, something is interfering with account access on webpages. Spent 3 hours with AT&T where they monitored trying to access my email account.

Could access with Edge, Chrome and Safari. However, Firefox is dead and will not allow me to access websites as pages do not load or interferes with account access.

Mozilla support needs to fix this issue ASAP or I will be forced to leave Firefox for good. I know I am not the only one having this issue! I was willing to put in the effort to verify if Firefox was actually broken or not!

Today I suddenly started receiving the error code: SEC_ERROR_REVOKED_CERTIFICATE on a secure authentication page that was working until a few hours earlier, belonging to a major national bank.

https://www.ssllabs.com/ssltest/ cannot reach that page, other SSL checking sites report variable results (some say one cert in the chain has expired after a CRL, others say all is OK)

The same page/site works flawlessly on Chrome. Firefox incompatibility with popular portals is a growing trend unfortunately.

After a little digging with developer tools, it comes out the OCSP query reports the REVOKED_CERTIFICATE error. Disabling the "Query OCSP [..]" option in Firefox that website starts working fine again.

Now, I would like to still keep using the OCSP queries ON, and I definitely want to keep using Firefox for everything.

My question is: when a portal or website is found to be broken with Firefox (with default settings), with a root cause found like in this case, how can it be reported?

Having a clear report path would be useful to try to make the browser more compatible (in this case : was this a bug? Some wrong information on OCSP responders? Some mess caused by the website mantainers?)

I want to delete all my bookmarks at once -- I have nearly 1,500. I already asked this question and the response I got showed me how to do this by selecting each one at a time. I want to delete them all, AT ONCE!

Not selecting each one and holding down the CTRL key.

Btw, I already explained this ... so, is there a way. I've tried uninstalling and reinstalling and not keeping the former settings. But the stupid bookmarks keep coming back!

My hotmail Email page stopped opening yesterday morning. I can open the Live.com page on my Android phone and Safari. I Don't like Safari, and I want to be on Firefox on my desktop.

I have used Firefox for years with no problems. The past month, however, I am encountering many problems with my often used web sites. What is going on? I make a purchase and cannot proceed. I have not added any new blockers or anything.

As the title states, certain media elements within Firefox refuse to play with audio, but only with frustrating inconsistency. For example, any videos on Youtube are fine. Any videos on Reddit are fine. But many videos, most commonly on boorus and streaming sites I cannot name here, will not play. The volume on the video slider is all the way up, the Firefox application is not muted, the site is not muted, and the tab is not muted. The only thing that makes those videos play audio is if I left click on them to open them in another tab by themselves. While it solves the issue, it's still an extremely inconvenient way to go about my browsing. I know for a fact that this is a Firefox problem because those same videos on those same sites work perfectly fine within other browsers. Please, does anybody know of a solution to this issue?

Firefox has become exceedingly slow. I have used Firefox for the most part going back to the beginning save a 2 year stint when Mozilla fell behind and did not update the product in the early years after ver 4. However, the slowness of Firefox is so bad now that I may have to find or use another browser! It is literally that bad! This problem is recent as in the last 45 days as far as my individual needs. I have already gone through the troubleshooting list and made the modifications. That seemed to work for a day or two but the slowness of Firefox is progressively getting worse with each passing day.

The speed is like 3 minutes to 10 minutes when just trying to open a known and commonly used bookmark. Checked against Edge which came with Win 11 and Edge loads within a second or two. So, the problem is not hardware or internet connection. I have one of the fastest speeds on the planet with a true fiber optic connection as I am close to the backbone location in my city. We are talking 2.1gig down and 820MB up. Tested against two different speed tests. The problem is with Firefox specific. Mozilla needs to address this issue as it seems to be an ongoing problem across several IOS platforms.

I have an mp4 (h264 AAC) video of 37MB which plays acceptably from my website in Safari, Chrome and Edge, but when played in Firefox (my default browser) the sound and picture synch is significantly seperated. When the video is compressed to 26MB it suffers some expected loss of sound quality but plays with near perfect lip synch. What is the issue with playback ?

Greetings Customer Service @ Mozilla While attempting to Turn on Mozilla Firefox Extension to Intensify the Detection Technologies through my Kaspersky Premium Software, I received the following error message:

Secure Connection Failed

An error occurred during a connection to addons.mozilla.org. The OCSP response is not yet valid (contains a date in the future).

Error code: SEC_ERROR_OCSP_FUTURE_RESPONSE

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

I would appreciate any assistance or feedback on this to determine a solution for the problem!

Hi,

I'm on OS Windows 11 and the latest version of FF (133). I also use NordVPN; I can access the web via Edge and Chrome with VPN, but for the last month, it doesn't work with FF. What could be the problem?

Hi,

I'm developing a website that needs to authenticate with an external endpoint. Once authenticated, the website receives a session cookie that it uses for subsequent API requests.

I've configured the CORS headers on both Apache and Nginx, but I can't get it to work in Firefox. Interestingly, the same setup works perfectly in Google Chrome.

Here's an example of the headers I receive using a curl call:

curl -X OPTIONS https://crlliria.moval.es/web/session/authenticate \ -H "Origin: https://gis.moval.es" \ -H "Access-Control-Request-Method: POST" -I -k

HTTP/1.1 204 No Content Server: nginx Date: Wed, 04 Dec 2024 10:23:24 GMT Connection: keep-alive Access-Control-Allow-Origin: https://gis.moval.es Access-Control-Allow-Credentials: true Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, DELETE Access-Control-Allow-Headers: DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range Access-Control-Max-Age: 1728000 Content-Type: text/plain; charset=utf-8 Content-Length: 0

Despite these headers appearing correct, Firefox throws the following error:

"Credential is not supported if the CORS header ‘Access-Control-Allow-Origin’ is ‘*’."

I know the Access-Control-Allow-Origin value is not * (it's set to https://gis.moval.es), so this message might not reflect the real issue. However, I can't figure out how to debug it further.

Questions:

Is there anything specific about Firefox's handling of CORS and credentials that might cause this issue? Are there tools or techniques I can use to diagnose the actual problem? Could there be a subtle discrepancy in the request or response that Firefox is stricter about compared to Chrome? Any help or suggestions would be greatly appreciated!

Thanks in advance.

Here's an example of the scenario I'm suffering: - You want to go do something on a website, say Bacefook (as a demonstration). So you go search up "Bacefook", and enter. - You use the Google search engine, as it does the job. However, you notice it has been taking a few seconds longer than anticipated. - Your internet times out and says it's having trouble connecting to the website. - You refresh, and suddenly the website perfectly loads.

Sometimes it even takes more than one refresh to get it to load normally! And this is not limited to the google search engine. It happens on all sorts of websites. There is no clear pattern to when a website actually loads or not. This problem is limited to my 2 WiFi routers, as other WiFi routers load all websites perfectly.

I decided to check the network tab in the inspect element for more information. I get "NS_ERROR_UNKNOWN_HOST" which is clearly false because the target website clearly exists. And the timings tab in the faulty request shows that every timing took 0 milliseconds to fulfill, so it may be the case that no data has been sent. (Seen in image below)

Chrome doesn't really have an issue with this. YouTube may have taken a long time to load in a test experiment though but it loaded successfully all along.

This also seems to be appearing elsewhere for a lot of internet request my computer makes, so it may be an internet setting that exists from one application from another. But it's been bugging me a lot with Firefox specifically.

This problem started happening about 1-2 months ago, and I use Firefox 131.0.3, the latest version of Firefox.
